Reason:
A physical I/O error has occurred during an attempt to read a physical record (block). Unless user-specified physical I/O error handling exists, processing is terminated.
For z/OS, if a block size has been specified in the IDD file entity or DD statement, this will override the actual data set block size, and if smaller, will cause an error. Also, if the input consists of concatenated data sets, the data set with the largest block size must appear first in the concatenation.
For z/VSE, a physical I/O error can be identified beginning with message ID DC507906.
Additionally, this error condition may also have been caused by a hardware malfunction or an erroneous attempt by ADSBATCH to read beyond the end of file.
Ensure that the block size, if specified in the IDD file entity or DD statement, is compatible with the block size and record format used to create the data set (check the data set label). If data sets are concatenated, ensure that the data set with the largest block size appears first.
